TEHRAN, March 16, YJC - Turkish President Recep Tayyip Erdogan on Thursday said the EU has started a crusade against Islam with a ruling on Islamic headscarves and warned the Netherlands that Ankara was no longer a friend, in a worsening diplomatic crisis.

TEHRAN, Young Journalists Club (YJC) - Turkey and the European Union are locked in their most explosive row in years after key EU members Germany and the Netherlands blocked Turkish ministers from holding rallies to win support for expanding Erdogan's powers in a referendum.

Ankara has expressed dismay over the rise of the anti-immigrant far-right in Europe but on Wednesday showed no pleasure over the election win of liberal Dutch Prime Minister Mark Rutte, with the crisis showing no sign of abating.

Erdogan accused the EU's top court of starting a "crusade" against Islam after a ruling that allows European companies to ban employees from wearing religious or political symbols including the Islamic headscarf.

"The European Union's court, the European Court of Justice, my esteemed brothers, have started a crusade struggle against the (Muslim) crescent," Erdogan said in a televised speech, AFP reported.

"Europe is swiftly rolling back to the days before World War II," he added.
